Fast and full-featured SSL scanner. Continuation of https://github.com/iSECPartners/sslyze.
SSLyze is a Python tool that can analyze the SSL configuration of a server by connecting to it. It is designed to be fast and comprehensive, and should help organizations and testers identify misconfigurations affecting their SSL servers.
Key features include:
- Multi-processed and multi-threaded scanning (it's fast)
- SSL 2.0/3.0 and TLS 1.0/1.1/1.2 compatibility
- Performance testing: session resumption and TLS tickets support
- Security testing: weak cipher suites, insecure renegotiation, CRIME, Heartbleed and more
- Server certificate validation and revocation checking through OCSP stapling
- Support for StartTLS handshakes on SMTP, XMPP, LDAP, POP, IMAP, RDP and FTP
- Support for client certificates when scanning servers that perform mutual authentication
- XML output to further process the scan results
- And much more !
SSLyze requires Python 2.7; the supported platforms are Windows 7 32/64 bits, Linux 32/64 bits and OS X 64 bits.
SSLyze is statically linked with OpenSSL. For this reason, the easiest way to run SSLyze is to download one the pre-compiled packages available in the GitHub releases section for this project, at https://github.com/nabla-c0d3/sslyze/releases.
The following command will provide the list of available command line options: $ python sslyze.py -h
$ python sslyze.py --regular www.isecpartners.com:443 www.google.com
See the test folder for additional examples.
SSLyze is all Python code but since version 0.7, it uses a custom OpenSSL wrapper written in C called nassl. The pre-compiled packages for SSLyze contain a compiled version of this wrapper in sslyze/nassl. If you want to clone the SSLyze repo, you will have to get a compiled version of nassl from one of the SSLyze packages and copy it to sslyze-master/nassl, in order to get SSLyze to run.
The source code for nassl is hosted at https://github.com/nabla-c0d3/nassl.
SSLyze can be packaged as a Windows executable by running the following command:
$ python.exe setup_py2exe.py py2exe
